Be it known that 1, WILLIAM D. Cook, a citizen of the L'nited States, residing at Se1- bert, in the county of Kit Carson and State of Colorado, have invented certain new and use-.

ful Improvements in Disk Plows, o'f-which the following is a specification. l

This invention relates to improvements in rotary lows, and is designed to provide a plow o the disk class whereina novel con-v struction of furrow-former or plow proper is employed to simplify the structure over prior implements usin a plurality of disks and to form a furrow which shall be smooth or free from the ridges or inequalities of surface pro duced when the ordinary disk plow is used,

means wherebythe plow may be adjusted to work at different diagonal angles to the line of draft and wherein scraper mechanism is proformer and vto turn it over in such a way as to serve the function of a moldboard.

In the accompanying drawings, Figure 1 is a top plan view of a plow embodying my invention. 2 2 of Fig. 1. Fig. 3 is a detail view, partly in side elevation and partly in section, showing the adjustable bearing for one end of the plow-shaft.

Referring to the drawings, the numeral '1 designates a front or main frame beam hav ing rearwardly-turned ends 2, carrying bearings 3 for the journals upon the ends of a 'field or traction roller 4, which roller is rovided with llanges 5 to enter the soil and mold the low from side draft or lateral deflection.

'llie rearwardly-turned ends 2 of the beam 1 are connected and braced by an arched central beam which is centrally connected with the beam 1 by a bracket 7, to which is suitably secured the rear end of a tongue or draft attachment 8, on which is supported a drivers seat 9.

A transverse beam 1() is arranged in rear of the roller in the lane of the beam 1 and is rovidcrl with lorwardly-turned ends 1], ringed to the ends 2 of the front beam, asindicated at 12, whereby the beam 1() is adapted to swing in a vertical plane. An adjusting-lever 13 is pivote-'i to the beam fl and carries a paw] to engage a rack 14, fixed to the beam 6, and is attached by a link 15 to the beam 10, by which the latter may be adjusted and supported in adjusted'position.

The beam 10A is provided at its opposite Fig. 2 is a section thereof on lineends with a short arm 16 and along arm 17,

which extend rearwardly therefrom, the arm' 16 being in the form of a braeketcarrying a bearing 18, in which is journaled a shaft 19, carrying a sprocket-wheel 20, said sprocketwheel 20 being connected with a, similar wheel 21 on an extended end of the shaft of the roller 4 by a chain 22.

The arm 17 is formed at its rear end with aslotted guideway 23, in which is slidably mounted a bearing-block 24, chambered to receive a bearing-sleeve 25, having trunnions 26 to turn therein. The rear end of the guideway 23 is closed by a cross-piece 27, removably secured thereto, and working in j this cross-piece and a stationary cross-piece and, further, to provide simple and effective 28 at the forward end of the guideway are adusting-screws 29 and 30, bearing on the lock and-whereby the latter may be moved forwardly or rearwardly, each screw being vided to remove the earth from the furrowprovided witha check-nut 31 to hold it in adjusted position.

The plow roper is arranged diagonally at the rear of t 1e frame and comprises a shaft 32, carrying a spiral furrow-cutting blade 33. One end of the shaft 32 is connected with the shaft 1) through the medium of a universal joint 34, while. the other end of said shaf t 32 is journaled in the bearing member 25, the construction thus being such that the plow or furr nv-former may be adjusted to lie at different diagonal angles to the line of draft and also swung vertically with the frame-bemn 1() to vary its depth of penetration ofthe soil and to hold it elevated above thel ground-surface during the trans )ortation of the implement from place to piace or to different portions of the field. Owing to the fact that the blade Zi is in the form of a cutting-screw whose portions are continuous, it will be readihvr understood that the earth eut away thereby will be conducted to one side and a furrow formed which will be entirely smooth or free from ridges.

l A scrapingdevice is arranged in rear of the cutting-blade and provided to remove the accumulated soil therefrom. lhis con'ipriscs an endless chain 555, passing around sproclwtwheels 36 and provided with a series of scraping wings or blades il?. The scraper as a IOO whole is carried by a suj)porting-frame comllO ' effect, a nioldlioard.

terminate in forwaiilly-projeeting arms 42, having sleeves 43, embracing the shaft 32, The sleeve adjacent the universal jointl S54 is provided with an arcuate slotted extension 44, which extends beneath. the beam l() and is connected thereto b v a bolt 45. This eX- tensioii H holds the scraper from independent pivotal movement on the shaft 2 and at the saine time permits of Vthe adjustment ol -said scraper with the shaft. 'l`hef scraperlingers 37 are arranged at the proper angle te traverse the working faces of the convolutions of the spiral blade 325 and act to remove the accumulated soil therefrom and to turn over the soil, so that said lingers will form, in As the spiral cutter 33 revolves the [langes or coiivolutions thereof will so act upon the 'lingers as to iinpa rt inotion to the chain 35, thus securing an easy aetion of the parts and a sullieient individual range of motion of the lingers to free them from the soil scraped from the. spiral cutter.

lt will of course be understood that the sprocket drive-gea ring may be proportioned to drive the shaft 32 and scraper at any desired rate o'f speed, and it will be seen that the construction described` provides a plow proper which will cut a perfect furrow free from ridges or other irregularities and which is adjustable at different angles of the frame to suit different conditions of service.
